Protect Critical Infrastructure Networks with TimeProvider 4100 Series v2.3

Microchip’s new timing grandmaster enhancements improve deployment flexibility, security and scalability

13 October 2021 – Infrastructure communication networks – 5G mobile, utilities, cable, transportation, defence and data centres – acquire and maintain signals for precise timing from Global Positioning System (GPS) or other worldwide satellite constellations. These networks require redundant backup systems when Global Navigation Satellite System (GNSS) signals are unavailable. The TimeProvider® 4100 Release 2.3 precision timing grandmaster available today from Microchip Technology Inc. (Nasdaq: MCHP) meets this requirement with the industry’s very latest IEEE® 1588 v2.1 2019 security standard for protection of timing systems, while also providing an increased level of deployment flexibility and scalability.

Introducing an ultra-resilient multi-client Precision Time Protocol (PTP) optional license, Microchip’s TimeProvider 4100 Release 2.3 grandmaster provides customers with up to three connections to other grandmasters in the operator’s network. This capability can be used as a backup for time and phase input. This new option implements the latest IEEE 1588 2.1 standard majority vote mechanism to select the best input for Assisted Partial Timing Support (APTS) backup protection.

Additionally, TimeProvider 4100 release 2.3 provides more deployment flexibility with support for two PTP server profiles on every Ethernet port. Customers can now optimise usage of these ports without additional hardware investments. Release 2.3 also allows PTP server, PTP client and in-band management to be used on a single port.

Providing increased security with support for the latest IEEE 1588 2.1 2019 standard, TimeProvider 4100 Release 2.3 includes support for architecture guidance security, which uses redundant communication paths between PTP nodes to detect tampering. It also implements out-of-band management mechanisms for detecting tampering, degradation and failures. This timing grandmaster provides complete support for authentication, authorisation and accounting (AAA) as well as two-factor authentication. As a software update, TimeProvider 4100 Release 2.3 is available for new and already-deployed systems. Other features include:

  • PTP enhancements including increased capacity of up to 1,000 network clients, which is required for certain applications such as data centres
  • Enhancements to the E1/T1 expansion module with new signals such as composite clock and JCC (Japan CC format), both inputs and outputs, for increased integration with legacy systems

TimeProvider 4100 Release 2.3 can be managed by Microchip’s TimePictra® Synchronisation Management System for full Fault, Configuration, Accounting, Performance and Security (FCAPS). Contact the Chronos team for more information.
